Below are its primary applications and detailed explanations: ---1. Production of Acetylene (Cac2) - Reaction Principle: Calcium carbide undergoes a vigorous reaction with water, generating acetylene gas and calcium hydroxide. - Applications: - Metal working: Acetylene-oxygen flames, boasting temperatures exceeding 3000°C, are pivotal for welding, cutting, and thermal spraying of metals. - Chemical Feed stock: Production of polyvinyl chloride (PVC), acetic acid, and acetone. Despite the dominance of ethylene-based processes, acetylene is indispensable for niche chemical syntheses. - Historical Use: Once a crucial fuel source for early mining lamps and signal lights. ---2. Metallurgical Industry - Desulfurizing Agent: In steel making, CaC2 efficiently reacts with sulfur to form calcium sulfide, lowering sulfur content in steel and enhancing ductility. - Reducing Agent: Serves as a reducing agent for metal oxides at high temperatures, facilitating metal extraction such as in ferroalloy production. ---3. Agricultural Applications - Fruit Ripening: Acetylene emitted replicates ethylene (a plant hormone), hastening the ripening of fruits like bananas and mangoes. -Soil Amendment: The alkaline byproduct, calcium hydroxide, neutralizes acidic soils. Caution is crucial to avoid excessive alkalinity. ---4.Production of Calcium Cyanamide - Fertilizer and Pesticide: At elevated temperatures, CaC2 reacts with nitrogen gas to synthesize calcium cyanamide, a slow-release nitrogen fertilizer and pesticide. ---5. Laboratory Uses - Acetylene Source: Supplies acetylene for organic synthesis, combustion experiments, and gas chromatography applications. - Safety Note: Acetylene possesses a wide explosive range (2.5-82% in air); hence, it demands rigorous ventilation and flame precautions. ---6. Other Applications - Carbon Source: Functions as a reactive carbon donor in specific chemical reactions. - Emergency Lighting: Historically significant in carbide lamps, now largely supplanted by battery-powered lighting systems. ---Safety Precautions - Storage: Secure storage in airtight, moisture-proof containers is essential (water contact releases flammable acetylene). - Handling: Always wear protective goggles and gloves to safeguard against skin/eye irritation from dust exposure. -Acetylene Risks: Highly flammable; ensure proper ventilation and steer clear of ignition sources. Calcium carbide's remarkable versatility renders it an indispensable asset across multiple industries. However, ensuring the utmost safety through adherence to strict protocols is vital in mitigating any potential risks.PropertiesThis compound appears as a solid mass in shades of gray, yellow, brown, or black. It possesses a density of2.22 g/cm 3. The compound may lose its luster, turning gray due to moisture absorption from the air. Additionally, it conducts electricity, showcasing a high degree of reactivity. It actively reacts with various gases and liquids under specific temperatures, with a notable reaction with water that produces Acetylene and calcium hydroxide.PackagingSealed hermetically in 50kg or 100kg iron buckets, these packages must be clearly labeled with "CALCIUM CARBIDE:""AVOID WATER AND FIRE" to ensure safety.Transportation CautionsIt is imperative to maintain packaging in excellent condition while storing the goods in a dry, cool, and well-ventilated space. To prevent any risk, keep it separate from combustible materials and acids. Avoid any water or moisture contact. The Acetylene within the iron drum should be released before storage. Prevent rolling drums, rough handling, or collisions to avert sparks that could initiate an explosion. An optimal storage timeframe ranges from 12 to 24 months.Handling Breakage and LeakageUpon breakage or leakage, promptly collect the material (using rubber gloves for safety). Thereafter, cleanse contaminated objects and areas thoroughly with running water.Emergency TreatmentIn cases of dizziness, headache, or nausea, move to an area with fresh air immediately. For severe symptoms, seek hospital care without delay.Fire Extinguishing Method:Utilize carbon dioxide, sand, or soda ash to effectively extinguish any fires.Important Remarks: UN NO. 1402CLASS 4.3 - FLAMMABLE ITEM
